The [EX: ] command can be used when two identical pantographs are shown in the original picture—one raised and one lowered.  The command [EX: ] creates "jumping" movements for both pantographs.  The coordinates <UpX>, <Y> are used to denote the raised pantograph's position and the coordinates <DownX>, <Y> for the lowered. Both rectangular areas have the size <W>, <H>. Regardless of which pantograph is raised and which is lowered in the original picture,  the pantograph which possess the smallest X coordinate is considered the first and the one with the largest X coordinate is considered the second. This is how the pantographs which are created by using the [EX: ] command are referred to and can be called by the program (see: Actions: Pantograph state changes).

If the <DownX> parameter is not specified Traffic will create a symmetrical position of the pantographs and determines the positions of the lowered pantograph accordingly.

The commands [EC: ], [ED: ], [EU: ], [EX: ], [EM: ], [EMC: ], [EMX: ] as well as the use of the _SAR pictures in the form <BasePicture> < <_SAR_Picture>  are only intended to facilitate the use of base pictures which were not specifically drawn for the traffic program. The preferred method of depicting pantographs in Traffic is by way of a series of phase pictures (which should be grouped into a single image containing all of the portions of the animation) in order to create a fluid, animated motion.  The second best method is to depict both pantographs in their lowered state and to draw each pantograph's raised state as a separate graphic.
